FLY-TRAP.

SPECIFICATION forming part of Letters Patent No. 645,880, dated March20, 1900.

Application filed October 21,1899- To all whom it'mrtg concern.-

Be it known that'l, CHARLES ETVARNUM, residing at Vinland, in the countyof Douglas and State of Kansas, have made certain new and usefulImprovements in Fly-Traps, of whichthe following is a specification.

My invention is an improvement. in flytraps, and has for an object toprovide a construction through which cows and other animals may pass andin which the flies will be brushed therefrom and pass into trapsarranged to receivethem and-which maybe removed in order to dispose'ofthe flies in any desired manner. L

The invention consists in certain novel constructions and combinationsof parts, as will be hereinafter described, and pointed out in theclaims. V I

In the drawings, Figure l is a perspective viewof atrapembodyingmyinvention. Fig. 2 is a vertical longitudinal section of thetrap. Figs. 3 and 4 are cross-sectional views on, respectively, aboutlines 33 and; 4 of Fig. 2. Fig. 5 is a detail horizontal section onabout line 5 5 of Fig. 2,'and Fig.- 6 is 'a detail view. I

In carrying out my invention 1 provide a chute A, through which theanimals may pass. The entrance of this chuteis controlled by avertically-sliding door B, atthe outside of which I'p'rovide atrapping-hood 0, having a connected trap O. The purpose of this hood 0is to catch such flies as maybe frightened, off the animal whileentering the chute. Slightly in rear of the entrance I provide theshades E, E, and E which darken the chute in front of the brushes, arepivoted at their upper ends, and are of diiferent lengths, as shown.These shades are arranged to be lifted against the action of the springG by the cord F, operated by the Windlass-shaft F, and the object ofthese shades is to darken the space in front of brushes, so the flieswill rise to the light above, as will be understood from the drawings.

Brushes H H are arranged in the chute in rear of the shades. Thesebrushes project inwardly from the opposite sides of the chute andincline rearwardly from their lower toward their upper ends and areshown as formed with their brushing edges slightly concaved. Thesebrushes conform generally to Serial No. 734,352. (No model.)

the cross-section of the animal-as it passes between them and operateefliciently in removing all the flies, which pass upward into thetrapping-compartment D, before referred to. Immediately in rear of theinclined brushes I provide the hinged doors I I. These doors are hingedat their front edges atJ to the chute and are pressed toward each otherat their rear ends by the'springs J. The doors thus con verge towardtheir rear edges and are provided on their inner forward faces next tothe i'nclinedbrushes with brushes K, which cooperate in removing theflies.

The meeting edges of the'doorsl and I are front of the chute to enterthe main trappingthe light from the rear end of the chute, so the flieswill pass up into the main trappingcompartment D. The shield M is hingedat its upper end and may be raised and lowered by means of the cord M.

The main trapping-compartment D fits over the chute and may preferablybe. readily detachable therefrom. This compartment extends fromimmediately in rear of' the entrance-door to a point over thelight-shield M has screen sides D, cross-partitions D and a top Dprovided with slots D which communicate with slots E in the trap-boxesN, which are fitted removably upon the compartment D. These trap-boxesare made of such size that they can be readily removed, and I providethem with the hinged plates N, which may be turned to open the slots Eto permit the entrance of the flies and to close such slots when it isdesired to remove the trap-boxes in order to dispose of the files, asmay be desired. The compartment D may be regarded as the trap proper andthe trap boxes N as cages to receive the trapped flies for disposal inany desired manner.

The apparatus may be portable or fixed, as desired.

I find it desirable to provide openings 0 in doors I and I, its purposebeing to exclude the sides of the chute, through which the animals maybe prodded to cause them to proceed through the chute.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A fly -trap substantially as described comprising a chute havingwithin it means for removing flies from cows and the like, atrapcompartment extending above said chute,and removable trap boxes orcages fitted 011 said compartment and having openings communicatingtherewith, and means for closing said openings at will substantially asset forth.

2. In a trap substantially as described the combination of a chute, atrapping-compartment above the same, adoor controlling the entrance tosaid chute, and a hood in front of said door substantially as set forth.

3. In a trap substantially as described, a chute provided withadjustable shades to darken the chute substantially as set forth.

4. A trap comprising a chute and brushes at the opposite sides thereofand inclining rearwardly from their lower to their upper endssubstantially as set forth.

5. The combination with the chute of the doors therein converging towardtheir rear ends and provided. on their inner forward sides with brushessubstantially as set forth.

6. The combination of the chute,the hinged shades therein, the inclinedbrushes, and

the hinged converging doors provided with brushes substantially as setforth.

7. A trap substantially as described comprising the combination with achute of doors hinged at their front edges and converging at their rearedges within said chute, provided on their front faces with brushes andhaving cut-away portions at the lower ends of their converging edgessubstantially as set forth.

8. The combination in a trap of the chute, inclined brushes andconverging doors therein, a swinging light-shield in rear of said doors,and the trapping-compartment above the chute substantially as set forth.

9. In a trap substantially as described the combination of the chute,the trapping-compartment above said chu te,and the trap boxes or cagesmounted on said compartment and removable substantially as described.

10. A trap substantially as described comprising a chute provided withmeans for removing flies from animals passing through the chute, and atrapping-compartment arranged above and extending lengthwise over thechute and trap boxes or cages fitted reinovably to said compartment andcommunicating therewith substantially as set forth.
